is the melting point different for each substance?

Yes, melting point varies significantly from one substance to another, though two different substances can have the same melting point. Melting point is a characteristic property of a substance, meaning that it is useful in identifying a substance. In most cases, melting point and freezing point are approximately equal. Melting point trends exist within substance groups. When looking at elements, non-metals tend to have lower melting points than metals. For compounds, those formed by ionic...

Melting point is a characteristic property of a substance, meaning that it is useful in identifying a substance. In most cases, melting point and freezing point are approximately equal. Melting point trends exist within substance groups. When looking at elements, non-metals tend to have lower melting points than metals. For compounds, those formed by ionic bonds have higher melting points than thouse that are covalently bonder. In both cases, exceptions exist.
